Lesson: Standard Molar Gas Volumes Chemistry

Students will be able to

• state the formula for calculating molar volume,
• calculate the molar volume of a gas from the gas volume and number of moles,
• recall that the standard molar gas volume at room temperature and pressure (RTP) is 24 dm³/mol,
• recall that the standard molar gas volume at standard temperature and pressure (STP) is 22.7 dm³/mol,
• describe what conditions constitute RTP and STP (RTP: 1 bar and 20 degrees Celsius, STP: 1 bar and 0 degrees Celsius),
• calculate the volume or number of moles of gases at RTP,
• calculate the volume or number of moles of gases at STP.
